DETAILED DESCRIPTION

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In this disclosure, unless otherwise stated, directional words such as "inside" and "outside" refer to the inside and outside of the contour of each component. Figure 3 The X direction in the duct plate can refer to Figure 3 The Y direction in the figure, the height direction of the air duct plate can be referred to Figure 3 The terms "first" and "second" are used to distinguish one element from another element and have no order or importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements, and this disclosure will not repeat them.

[0028] In the related art, the refrigeration assembly of a refrigerator generally includes an air duct cover, an air duct plate and a volute, wherein the air duct plate is arranged on the air duct cover, and the volute is arranged on the air duct plate, and forms an air supply cavity with the air duct plate, wherein the volute is connected to the air duct cover by fasteners. In this way, the volute needs to have a through hole that cooperates with the fastener, which causes the cold air in the air supply cavity to easily leak from the through hole. Therefore, the air tightness of the refrigeration assembly itself in the related art is poor, and cold air is easily leaked, thereby reducing its own refrigeration effect.

[0029] In order to solve the above technical problems, the present disclosure provides a refrigeration assembly, referring to Figures 1 to 4 As shown in the figure, the refrigeration assembly includes an air duct cover plate 1, an air duct plate 2 and a volute 3. The air duct plate 2 is arranged on the air duct cover plate 1, the volute 3 covers the air duct plate 2, and forms an air supply cavity 10 with the air duct plate 2. The volute 3 includes a split shell 31 fitted with the air duct plate 2, and a clamping structure 4 is arranged on the side of the split shell 31 facing away from the air duct plate 2. The split shell 31 is clamped with the air duct cover plate 1 through the clamping structure 4.

[0030] Through the above technical scheme, in the refrigeration assembly provided by the present disclosure, the volute 3 can surround part of the duct plate 2 by using the fitting of the split shell 31 and the duct plate 2, wherein the split shell 31 can be clipped with the duct cover plate 1 through the clip structure 4, so that the split shell 31 can be tightly fitted on the duct plate 2 by using the pre-tightening force provided by the clip structure 4, and since the clip structure 4 is arranged on the side of the split shell 31 away from the duct plate 2, on the one hand, the clip structure 4 can replace the implementation method of connecting the volute 3 and the duct cover plate 1 with fasteners in the related technology, eliminating the step of drilling holes on the volute 3 to match the fasteners, and on the other hand, it can avoid that the clip structure 4 affects the fitting of the split shell 31 and the duct plate 2. Therefore, it can prevent the cold air in the air supply cavity 10 from leaking through the fitting of the split shell 31 and the duct plate 2, so that the above arrangement can improve the air tightness of the refrigeration assembly, solve the technical problem that the refrigeration assembly is prone to leaking cold air, and improve the refrigeration effect of the refrigeration assembly.

[0031] It should be noted that the air duct plate 2 in the present disclosure may be provided with an air outlet channel 22, and the cold air in the air supply cavity 10 may be blown into the refrigerator box 20 via the air outlet channel 22, and the present disclosure does not impose any limitation on this.

[0032] In some embodiments of the present disclosure, reference Figure 3 and Figure 4As shown in , the air duct plate 2 can be provided with side wall surfaces 21 on both sides perpendicular to its own thickness direction, and the sub-shell 31 can include a first side panel 311 that fits each side wall surface 21, and a clamping structure 4 is provided on the side of the first side panel 311 that faces away from the side wall surface 21. In this way, by using the two first side panels 311, the sub-shell 31 can be surrounded on the two side wall surfaces 21 of the air duct plate 2 from the above-mentioned thickness direction, thereby increasing the surrounding area of ​​the air duct plate 2 by the sub-shell 31, thereby further reducing the possibility of cold air leakage from the refrigeration component. In addition, each first side panel 311 can be clamped with the air duct cover plate 1 through the clamping structure 4, thereby also improving the stability of the connection between the volute 3 and the air duct cover plate 1.

[0033] In some embodiments of the present disclosure, reference Figure 3 and Figure 4 As shown in , the air duct cover plate 1 may include a second side plate 11 attached to the first side plate 311, and a clamping structure 4 is provided between the second side plate 11 and the first side plate 311 on the same side. In this way, the pre-tightening force provided by the clamping structure 4 can be used to make the second side plate 11 and the first side plate 311 on the same side fit tightly, so that even if cold air flows out from the fitting of the side wall surface 21 and the first side plate 311, the above arrangement can prevent the cold air from leaking through the fitting of the first side plate 311 and the second side plate 11, that is, the above arrangement can further reduce the possibility of cold air leakage from the refrigeration component.

[0034] In some embodiments, reference Figures 3 to 5 As shown in , the snap-fit ​​structure 4 may include a snap 41 and a slot 42 arranged in pairs, and one of the first side plate 311 and the second side plate 11 is provided with the snap 41, and the other is provided with the slot 42. In this way, the snap-fit ​​of the first side plate 311 and the second side plate 11 can be achieved by snapping the snap 41 with the slot 42, and the structure is simple and easy to implement. Here, the present disclosure does not impose too many restrictions on the specific structure and shape of the slot 42 and the snap 41.

[0035] In some embodiments, reference Figures 3 to 5 As shown in , the second side plate 11 may be provided with a slot 42, and the first side plate 311 may be provided with a buckle 41, wherein the first side plate 311 may also be provided with a sinking groove 312, and the buckle 41 is arranged in the sinking groove 312, and extends out of the sinking groove 312 in a direction close to the slot 42, and is engaged with the slot 42. In this way, by adding the sinking groove 312, the buckle 41 can be partially arranged in the sinking groove 312, so as to increase the structural strength of the buckle 41, and improve the stability of the first side plate 311 after being engaged with the second side plate 11, and can prevent the buckle 41 from extending too far out of the slot 42.

[0036] In some embodiments, reference Figure 3 and Figure 4As shown in , the air duct plate 2 may be provided with side wall surfaces 21 on both sides of its width direction, and multiple pairs of buckles 41 and slots 42 may be provided between the first side plate 311 and the second side plate 11, and the multiple pairs of buckles 41 and slots 42 are sequentially spaced in the length direction of the air duct plate 2. In this way, the close fit between the first side plate 311 and the second side plate 11 can be further ensured, thereby further reducing the possibility of cold air leakage from the refrigeration component. In some embodiments, three pairs of buckles 41 and slots 42 may be provided between the first side plate 311 and the second side plate 11, and the present disclosure does not impose too many restrictions on this.

[0037] In some embodiments of the present disclosure, reference Figure 2 and Figure 3 As shown in , the refrigeration assembly may include a fan 5, which is partially arranged in the air supply cavity 10, and the rotation axis of the fan 5 may extend along the thickness direction of the air duct plate 2, wherein the fan 5 has a thickness in the thickness direction of the air duct plate 2, and the ratio of the thickness of the fan 5 to its own diameter may be 0.160-0.180. Here, in order to ensure the air supply volume of the air supply cavity 10, the diameter and thickness of the fan 5 are generally flexibly designed, wherein the present disclosure sets the thickness of the fan 5 to its own diameter to 0.160-0.180, that is, the fan 5 of the present disclosure can ensure the air supply volume of the air supply cavity 10 when the diameter is large, at this time, based on the above ratio, the thickness of the fan 5 of the present disclosure can be designed to be smaller, thereby facilitating the reduction of the thickness of the entire refrigeration assembly, thereby facilitating the realization of the ultra-thin design of the refrigeration assembly, so that when the overall thickness of the refrigerator is constant, the thickness of the refrigeration assembly is reduced, that is, the storage space in the box 20 can be increased, and the effective use volume of the refrigerator can be improved. In some embodiments, the ratio of the thickness of the fan 5 to its own diameter can be 0.165, 0.168, etc., and the present disclosure does not limit this. In other embodiments, the ratio of the thickness of the fan 5 to its own diameter can be less than 0.260, for example, less than 0.256, and the present disclosure does not limit this.

[0038] In some embodiments of the present disclosure, reference Figure 2 As shown in , the thickness A1 of the fan 5 may be 20 mm to 22 mm, for example, 21 mm, which is not limited in the present disclosure.

[0039] In some embodiments of the present disclosure, reference Figure 2 As shown in , the air supply cavity 10 may have a thickness in the thickness direction of the air duct plate 2, and the thickness A2 of the air supply cavity 10 may be 19 mm to 21 mm, for example, 20 mm, which is not limited in the present disclosure.

The evaporator 6 may have a thickness in the above-mentioned thickness direction. The thickness A3 of the evaporator 6 may be 33mm to 37mm, for example, 35mm. In this way, the thickness of the evaporator 6 of the present disclosure is relatively thin, which is conducive to reducing the thickness of the entire refrigeration assembly, thereby facilitating the realization of an ultra-thin design of the refrigeration assembly. In some embodiments, the volute 3 and the evaporator 6 may be arranged in sequence in the height direction of the air duct plate 2, wherein the projection of the volute 3 in the height direction may partially overlap with the projection of the evaporator 6 in the height direction, thereby facilitating the reduction of the thickness of the entire refrigeration assembly, thereby facilitating the realization of an ultra-thin design of the refrigeration assembly.

[0041] In some embodiments of the present disclosure, reference Figure 2 As shown in , the refrigeration assembly may include an evaporator 6 and a sponge 7. The sponge 7 is arranged between the air duct plate 2 and the evaporator 6, and may be provided with a metal foil 71 that fits the evaporator 6. In this way, when the temperature of the evaporator 6 is low, the metal foil 71 can prevent the evaporator 6 from frosting, so that the defrosting efficiency of the evaporator 6 can be improved. Among them, the setting of the sponge 7 can play a role in heat preservation and heat insulation on the one hand, and on the other hand, the sponge 7 can be properly deformed, which is conducive to the assembly of the evaporator 6 and the air duct plate 2. In some embodiments, the above-mentioned metal foil 71 can be an aluminum foil, that is, the above-mentioned sponge 7 can be an aluminum foil sponge.
